HorizonVis – Interactive Visual Exploration of Multivariate Medical Measurements in Diabetes CareMultivariate, time-oriented data plays a central role in many domains such as medicine, finance, or environmental engineering. Information Visualization can be an instrument to make such vast datasets intuitively comprehensible. As the number of time series increases, visualizations need to be space-efficient. Horizon graphs [Reijner, 2008] are an innovative approach to reduce required space by dividing the a chart into bands and layering these. |

HypoVis: Modeling Hypotheses with Visual Analytics MethodsThe primary goal of Visual Analytics is the close intertwinedness of human reasoning and automated methods. Our goal in HypoVis is the design and development of a Visual Analytics process that uses the inherent structure contained in time-oriented data as a way to improve the integration of human reasoning. This structure can, for example, be seen in the calendar aspect of time being composed of smaller granularities, like years and seasons. Our focus is the generation of models from hypotheses, consisting of bringing the hypotheses into an automated system, and validating it. |

in2vis - Interactive Information Visualization: Exploring and Supporting Human Reasoning ProcessesUsers are confronted with a huge amount of abstract, but highly structured data. They want to accomplish different kinds of tasks, where they need different interactions and navigations as well as different views of the same data to gain more insight into the data under investigation. These processes of investigation are very complex and only little guidance exists. Therfore our aims are |

InfoVis Tools - A Detailed Comparison of Information Visualization Tools Using a Reference Data SetMany approaches to solve the problem of visualizing time-oriented data have been published in recent time, creating the need to categorize not only the methods to visualize time-oriented data but also the information visualization tools available on the market. Because of the difficulty of comparing such tools no agreement on a common categorization has been reached. This master's thesis uses a recently published categorization to perform a detailed comparison of several visualization tools, focusing on the temporal aspects of data. |

LASSIE – modeLing treAtment proceSSes using Information ExtractionModeling clinical guidelines and protocols in a computer-interpretable format is a challenging, but burdensome and time-consuming task. Existing methods and tools to support this task demand detailed medical knowledge, knowledge about the formal representations, and a manual modeling. Furthermore, formalized guideline documents mostly fall far short in terms of readability and understandability for the human domain modeler. |

PDF2Table – Utilizing Table PatternsIf we surf the web we can find PDF files in heaps. Once technical details of an amazing five mega pixel digital camera, once a statistic about the last two years incomes of an enterprise, and once a brilliant crime novel of Sir Arthur Conan Doyle is saved in a PDF file. The widespread use of this file format takes the focus on the question of how to reuse the data in such a file. Many things are already done in this area. For example, there are several tools that convert PDF-files to other formats. |

PlanViewer - Treating Temporal Uncertainties of Complex Hierarchical Data Visually
The visualization was developed with two open-source toolkits: The InfoVis Toolkit and Prefuse. The InfoVis Toolkit provides a memory saving data table used to store abstract data, prefuse is the base framework for all graphical issues. The application was developed in the scope of a thesis about temporal uncertainties in plans. Generally, there are three ways on how to treat temporal uncertainties: |

polycube - Towards Integrated Mental Models of Cultural Heritage DataWeb-based databases of museums’ and cultural institutions’ collections enable fast access to important cultural assets for everyone: Millions of paintings, sculptures, music, and artworks can be reached with only a few clicks. Current research shows that interested visitors like to explore digital collections - often without a concrete goal. They like their observations to add up and make sense and to learn something new. |

Smart Communities and Technologies (SmartCT)Cities are ever-evolving, complex cyber physical systems of systems covering a magnitude of different areas. The initial concept of a smart city started with cities utilizing communication technologies to deliver services to their citizens and evolved to using information technology to be smarter and more efficient about the utilization of their resources. In recent years however, information technology has changed significantly, and with it the resources and areas addressable by a smart city have broadened considerably. They now cover areas like smart buildings, smart traffic systems and roads, autonomous driving, energy hubs, electric car utilization, water/waste and pollution management, as well as concepts like urban farming. Therefore, we must enable an open adaptive interconnected approach that is able to incorporate new areas on demand overcoming potentially limiting compartmentalization. Smart cities exchanging their capabilities in an organic elastic manner, being able to address whatever challenge and opportunity they face with the expertise, data, and knowledge of a global network of expert stakeholders form the basis of our vision for an Internet of Cities. Our central focus is to create the scientific underpinnings for a future Internet of Cities infrastructure. We will create a comprehensive set of methodologies, models, and tools for design, development, management, and evolution of next-generation smart city applications. |

Social RewardingWikipedia - the most famous free encyclopedia - has been grown to the biggest wiki community site where hundreds of thousands of users all around the world post and edit articles in many different languages. As other online communities have troubles motivating users to participate actively, the tremendous contribution rate on Wikipedia has led to many problems like wrong information, copyright violations, or users' misbehavior, for example, spammers or trolls. |

TrainVis - Interactive visualization of train schedulesTimetables for trains or airplanes are often represented astextual tables. These contain usually all important information, however it is often not easy to find answersto more specific questions, like for example - "which train should I taketo travel from Vienna to Paris as quick as possible without changing the train twice?" - Humans can process visual information better than text and that?s why our application shall facilitate the process of understanding and searching a timetable. |
